Endogenous adenosine, which accumulates during hypoxia and ischemia, may perpetuate asystole. Therefore, patients with cardiac arrest were prospectively studied to see if their immediate outcome could be improved with aminophylline, a competitive antagonist of adenosine. Fifteen consecutive patients with cardiac arrest due to asystole or to nonperfusing bradyarrhythmias, who failed to respond to intravenous atropine and epinephrine, were treated with aminophylline (rapid intravenous injection of 250 mg). Establishment of a stable heart rhythm with sufficient blood pressure to allow discontinuation of closed-chest cardiac massage was achieved in 11 of 15 (73%) patients. All these 11 patients were alive 60 minutes after resuscitation. One patient survived, without neurologic damage. We conclude that the immediate outcome of patients with asystole refractory to standard treatment may be improved with aminophylline. Further study is warranted to determine if earlier administration of aminophylline during cardiac arrest will improve long-term outcome.
